The coin contains an actual meteorite that fell to Earth around 4,000 years ago in the Campo Del Cielo (Field of Heaven) in Argentina. It carries a $5 legal tender face value in Australia, but its collectible value is obviously much, much more. Blending fine silver (.999 fine that is) in a proof strike together with material from space that fell to our planet nearly 4,000 years ago makes a wonderful collectible coin that is a must have for any serious coin collector's collection.
